Non-linear electric conduction in the SDW phase of (TMTSF)2NO3

The non-linear electric conduction with the threshold electric field E T was investigated by the four-wire method in the Spin-Density-Wave phase of (TMTSF) 2 NO 3 . The temperature dependence of E T shows a peak around 0.3T SDW (T SDW = 9,6 K), although E T decreases with decreasing temperature below T SDW . This anomaly around 0.3T SDW indicates the change of electrical transport of SDW. We discuss this anomaly from the viewpoint of the multiphase of SDW phase.
